Install Apache OpenOffice 3.4.1 from PPA in Ubuntu/Linux Mint

In this guide, we will see how to install Apache OpenOffice 3.4.1 from PPA in Ubuntu/Linux Mint. I have only managed to add the 32-bit version of OpenOffice to the PPA and for the 64-bit version, you can see below how to install it manually. If you are satisfied with LibreOffice, then I recommend that you don't install OpenOffice because in terms of features and functionality LibreOffice is the best choice for you.
